Certainly they are susceptible to criticism, and not making a turing 
complete validation mechanism is one of them. But at least recognize 
that (for better and for worse) they tried to take a "middle ground" 
approach. XSD got a huge amount of criticism for being too complex 
(compared to DTDs), and adoption of it has been slow, largely for that 
reason. They were justly leery of adding even more complexity.

Of course a case can be made that a good language designer could have 
come up with a better, simpler, turing complete schema mechanism, but 
such is frequently the problem with design by committee. Look at the 
long torturous journey that C++ has taken navigating between the shoals 
of complexity and whirlpools of insufficiency.
